hello! i've been having problem playing the game world of warcraft, i've been playing for 10 months now and the last month i started to get a crash every 15-30 min. i checked the my event viewer and this comes out

Details
Product: Windows Operating System
Event ID: 51
Source: Disk
Version: 5.2
Symbolic Name: IO_WARNING_PAGING_FAILURE
Message: An error was detected on device %1 during a paging operation.

any info on fixing this would be greatly appreciated

I'm not postive, but the paging failure could be because you don't have enough paging file on your computer. Try right-clicking my computer > properties > advanced > setting (under performance) > advanced tab > change...make sure your minimum is about 1.5x what your RAM is. Hope that helps.
